description The invention discloses a pretreatment method for oily sludge on a horizontal screw filter pressing type offshore platform. The method includes respectively injecting a medicament A and a medicament Binto a medicament A storage tank and a medicament B storage tank, stirring and mixing, injecting a medicament dose into a pipeline mixer A and a pipeline mixer B according to a certain proportion, and fully mixing and injecting the medicament into a medicament mixing reactor; injecting oily sludge into the medicament mixing reactor through a feed pump, and crushing part of oily particles by the feed pump; fully mixing and reacting the injected medicament and the oily sludge in the medicament mixing reactor; conveying a supernatant fluid in the medicament mix reactor to an air float on the offshore platform to preform production water treatment; further pressing and concentrating sludge generated by sedimentation and flocculation in the medicament mixing reactor, and conveying the sludge to a pressure filter for p
